mb/google/drallion: Configure IRQs as level triggered for HID over I2C
As per HID over I2C Protocol Specification[1] Version 1.00 Section 7.4, the interrupt line used by the device is required to be level triggered. Hence, this change updates the configuration of the HID over I2C devices to be level triggered.
